    "I would not hesitate to contact Varsity again. They fixed issues left behind by another service (NJM). They did not tell me my boiler needed to be replaced nor did they sell me parts I didn't need. It was truly the best repair service experience I've ever had from the first phone call to meeting the fantastic techs, Steve and Matt. Very happy to recommend them and to let others know that they can 100% rely on Varsity Home."

I found Patience hvac Inc when I was about to lose hope. He is super fair and through, went over explanations of each parts replacement needed, did maintenance clean up of boiler and extra miles on my 30 years old boile now it is back life just like new. I am really thankful to Anthony. He is quick, prompt, sincere and humble. Trust me call this guy, You will save lots of money and headache."

    "I am not a dramatic person, but Cole is a godsend!! He was on time and diagnosed and fixed our issue quickly!! He was friendly, professional and BRILLIANT. Don’t let his young age fool you. This guy knows what he’s doing. My mom’s front porch light blew out from an overzealous space heater. And it wasn’t just the front porch light. None of the outlets on the entire front wall of the house were working! Thank you, space heater. So we saw the great reviews for Cole and decided to call him. BEST. DECISION. EVER. Cole arrived ON TIME and found the issue almost immediately. If you saw my mom’s house (bless her heart) you would know this was no easy feat. So thank you, Cole, for smashing the stereotype of the expensive electrician who milks the clock. You are, and always will be, our first call for all of our electrical needs. From the bottom of our hearts, thank you!!"

    "Ray was friendly and very professional and you can tell immediately that he was very customer oriented. As far as prices go, he was more than fair compared to the other bids. As a matter of fact I expanded the scope of his work to include a new water heater too. All the equipment supplied was 100% new, still in the factory cartons and the installation work was TOP QUALITY. Ray not only sold me the job but he did the installation too. He and partner Ken, and their assistant (3 man crew total) worked very professionally and effectively. Needless to say I HIGHLY RECOMMEND THEM."

    "My name is Irving Francis. I got in touch with Professor Pipes when my radiators got clogged in my house. After paying $225 to another techy from another company who claimed I needed new bleeders and getting the run around by 3 others so call heating experts.Professor Pipes reached out to me and I told him the problem and Mike diagnosed it as a simple line bleed. He fixed the problem and Im sitting in a nice warm home tonight. I highly recommend Professor Pipes to anyone having a heating problem. Mike is honest and fair when it comes to pricing. I highly recommend Professir Pipes."

He took the time to explain the problem, and what he would recommend to fix the problem. I was very satisfied with the results. The price for the fix was fair, I've already talked with him about having some electrical work done in the future."

    "Roberto and his team did an outstanding job today at my mother's home; from his initial reply throughout the entire process he was awesome. They removed her old boiler and replaced it with a new one; he even cleaned the entire surrounding area that had suffered from previous attempts to soak up the oil and/or water leakage. They ensured everything was working well. Mom has heat and hot water again and is very, very happy! Roberto even fixed the door leading from the garage into her home- WOW! Mom and I wanted to cry because of his generosity and kindness. Roberto totally went above and beyond and provided us with an overall exceptional customer service experience. We are extremely satisfied, and I highly recommend Roberto and will definitely use his services again in the future; the timeliness, value and quality of work, cleanliness and professionalism are all outstanding. He showed up on time and even finished a little earlier than promised which was very nice because it was cold in the home. Thank you, again, Roberto!"
